Abstract
"MóDULO DE INTERFACE DE RECEPçãO PARA USO EM UM DISPOSITIVO DE COMUNICAçãO DE MULTIMODOS E MULTIBANDAS, MéTODO PARA MELHORAR A RECEPçãO DOS SINAIS DE COMUNICAçãO EM UM DISPOSITIVO DE COMUNICAçãO DE MULTIMODOS E MULTIBANDAS, DISPOSITIVO DE COMUNICAçãO DE MULTIMODOS E MULTIBANDAS, E, DISPOSITIVO DE COMUNICAçãO PORTáTIL". Módulo de interface de recepção possuindo um ou mais caminhos Rx de 2GHz e um ou mais caminhos Rx WCDMA para uso em um dispositivo de comunicação portátil, tal como um telefone móvel ou um comunicador. O módulo compreende ao menos dois pontos de alimentação operativamente conectados a duas antenas eletricamente separadas para receber os sinais de comunicação. O módulo também compreende filtros para filtrar os sinais de comunicação na banda de freqüência correspondente, e um dispositivo para prover o isolamento da banda cruzada. O isolamento da banda cruzada é alcançado, por exemplo, ao usar amplificadores lineares nos diferentes caminhos de sinal. Vantajosamente, o módulo compreende três caminhos de sinal, de forma que um ou mais módulos podem ser usados juntos para alcançar a funcionalidade de MIMO/diversidade.
